R2noharm.EAP {sirt}

EAP Factor Score Estimation

Description

This function performs EAP factor score estimation of an item response model estimated with NOHARM.

Usage

R2noharm.EAP(noharmobj, theta.k=seq(-6, 6, len=21), print.output=TRUE)

Arguments

noharmobj

Object of class R2noharm or noharm.sirt

theta.k

Vector of discretized theta values on which the posterior is evaluated. This vector applies to all dimensions.

print.output

An optional logical indicating whether output should be displayed at the console

Value

A list with following entries

person

Data frame of person parameter EAP estimates and their corresponding standard errors

theta

Grid of multidimensional theta values where the posterior is evaluated.

posterior

Individual posterior distribution evaluated at theta

like

Individual likelihood

EAP.rel

EAP reliabilities of all dimensions

probs

Item response probabilities evaluated at theta
